Polyvinyl Alcohol PVA BP20

Polyvinyl alcohol (abbreviated as PVA) also can be called PVAOH. PVA is unique among polymers (chemical compounds made up of large, multiple-unit molecules) in that it is not built up in polymerization reactions from single-unit precursor molecules known as monomers. Instead, PVA is made by dissolving another polymer, polyvinyl acetate, in an alcohol such as methanol and treating it with an alkaline catalyst such as sodium hydroxide. There are several brands of PVA in the world, and China PVA is one of best one.Our PVA1788, PVA2088, PVA2488 can replace PVA BP17, PVA BP20, PVA BP24.
